B)z-score
C)variance
D)percentile

Quizplus · Accepted Answer

The z-score is a measure of how many standard deviations an individual data point is away from the mean of the data set. It is calculated as the difference between the data point and the mean, divided by the standard deviation. This makes it a useful tool for comparing values across different data sets, and for identifying outliers or extreme values within a single data set. The other options listed – coefficient of variation, variance, and percentile – are all related to measures of central tendency and spread within a data set, but do not specifically capture the distance of a particular value from the mean in terms of standard deviations.
